HYDRANT.

SPECIFICATION forming part of Letters Patent No. 694,298, dated February25, 1902.

Original application filed April 27, 1900, Serial No. 14,577. Dividedand this application filed December 14, 1900. Serial No. 39,859. (Nomodel.)

To all whom it-mcty concern:

Beit known thatI, DENIS F. OBRIEN, a citizen of the United States,residing at Newark, county of Essex, and State of New Jersey, haveinvented certain new and useful Improvements in Hydrants, fullydescribed and represented in the following specification and theaccompanying drawings, forminga part of the same.

The invention of this application (which is a division of an applicationfiled by me April 27, 1900, Serial No. 14,57 7) relates to improvementsin hydrants, and particularly hydrants of that class known ascompression-hydrants -that is, hydrants in which the main valve is heldto its seat by the pressure of water behind it.

The object of the present invention is to provide a hydrant of thisclass in which the main valve and connected parts are so constructed andarranged in the hydrant-casing that the main valve may be readilyremoved from or inserted in the casing without taking the latter apart,and, further, to provide an inserting and removing tool for the mainvalve which will not only unscrew it from or screw it into the openingprovided in the casing for receiving it, but will also interlock withthe main valve in such way as to support it while being removed from orinserted in the casing.

In the accompanying drawings, Figure 1 is a sectional elevation of ahydrant provided with a main valve constructed in accordance with thepresent invention. Fig. 2 is a similar view with the upper part of thehydrant or hydrant-casing removed and illustrating a main-valve removingand inserting tool constructed in accordance with the present inventioninserted in the casing. Fig. 3 is an elevation of the lower portion orfoot of the main-valve removing and inserting tool, illustratingparticularly the means with which it is provided for engaging androtating the valve and connected parts to screw them into or out ofposition in the casing. Fig. 4. is a bottom plan view of the same. Fig.5is a plan view of a seat-ring for the main valve.

Referring to said drawings, the hydrant or hydrant-casing therein showncomprises a casing or stand-pipe 1, provided with the usual hose-nozzles2 3, a main-valve casing 4, and a removable cap 5.

6 represents the main valve, the seat 7 of which is formed in anexteriorly-threaded ring 8, screwed into the main-valve casing, saidmain valve 6 being also provided with vertical guides 9 for maintainingit in proper relation to its seat when the valve is being closed oropened. The mechanism for opening and closing the mainv valve includes aspindle 10, secured to the valve 6, and an actuating-spindle 11,connected at its lower end with the spindle 10, so that as the spindle11 is rotated the spindle 10 rotates with it. The spindle member 11,which,as will be observed, passes through an opening in a bridge 13 anda stuffing box or gland 14. above the same, is threaded at its upper endfor connection with a turning-nut 12 and also for connection with aremoving-tool, hereinafter described, whereby the spindle, main valve,and the latters seat-ring are locked to and supported by theremoving-tool when the latter is in serted in the hydrant-casing for thepurpose of inserting or removing the main valve, as will hereinaftermore fully appear.

The hydrant and main-valve-operating mechanism shown and thus farbriefly described are not claimed herein, as they form thesubject-matter of my aforesaid application, wherein they are more fullydescribed.

For the purpose of providing for the ready removal and insertion of themain valve without taking apart the hydrant-casing or removing thestand-pipe 1 I construe tthe ring 8, containing the valve-seat 7, withvertical lugs 31, and also provide a tool adapted to engage said lugs 31and through them to rotate the ring 8 and screw it into or unscrewitfrom the main-valve casing. This tool consists of a pipe 32, adapted tobe passed over the spindles 1O 11 and provided at its upper end with. ahead 33, bearing handles 34, by which the pipe 32 may be rotated, and atits lower end with feet or lugs 35, adapted to engage with the lugs 31on the ring 8 to rotate the latter and unscrew it from or screw it intoposition in the casin g. To insert the tool into the hydrant-casing inengagement with the ring 8, the only parts of the hydrant which it isnecessary to remove are the cap 5, turning-nut 12, bridge 13, and arm28. 32 is then passed over the spindles 1O 11 and held in position bythe return to the spindle 11 of the turning-nut 12, as shown in Fig. 2,which by reason of its engagement with the threaded end of spindle 11looks the main valve and its seat-ring 8 to the removing-tool 2, so thatthey will be supported by the latter while being passed inwardly oroutwardly through the stand-pipe 1 to introduce them into or remove themfrom the hydrant. The tool 32 being turned will by the engagement of itsfeet 35 with projections 31 on valveseat ring 8 rotate the latter, andthus screw it into or unscrew it out'of engagement with the main-valvecasing. When unscrewed, the seat-ring 8 and main valve 6 are supportedand lifted out of the stand-pipe 1 by means of the removing-tool 32 andreintroduced by the same means. The pipe 32 is maintained in verticalposition or centered by means of a guide 36, secured to the spindle 10,aided by the bracket 18.

What I.claim is-- 1. In a hydrant, the combination with its stand-pipe,of a main-valve mechanism capable of being passed inwardly and outwardlythrough the stand-pipe to introduce it into andremove it from thehydrant and provided with a screw-threaded member for connection to thehydrant and with means for interlocking with a removing and insertingtool whereby said screw-threaded member may be rotated to connect it toor disconnect it from the hydrant and with means whereby said valvemechanism may also be supported by the tool while being introduced intoor removed from the hydrant, substantially as described.
